The triangular cocktail glass, what many people think of as the classic "martini glass", didn't really catch on until the Fifties. The curved-bottomed coupe, what Marliave uses for most of its up cocktails, is actually more authentic for a place trying to recall its pre-Prohibition roots. (Check out the old movies; The Thin Man drinks his martinis out of coupes.) You'll see those glasses at a lot of high-craft cocktail bars these days. I like them, am trying to find some for my home bar, preferably vintage, but I'd settle for new.
